My husband lower back

Just needed some advice really ... so this could all be related or maybe not . Just want to see if anyone has had any of these symptoms . My husband hates going to doctors, hates a fuss and would rather suffer , i on the other hand have to watch him in pain and it's awful . Over the last month he had had very bad lower back pain (he told me only is back hurt.) one day I walked passed the bathroom and heard him kinda yelping in pain whisky going to the toilet (wee) . When he came out I asked why the noise etc and he said he strains just to go for a wee , these has also been going on for 4 weeks. Previous to this he bleeds from his bottom when he goes to the toilet . (Not every time ) He has also been sick after food, for no reason . This has stopped now but did go on for a matter of weeks . I need to get him to doctors but he says it's just a bad back and he isn't tell doctor he strains to go to the toilet . Has anyone had this?? Am I being dramatic ?? I'm really worried . (Please excuse my grammar and spelling if it's not correct , I'm dislexic
